in order to study of effects of deficit irrigation on morphological traits and growth indices variation of corn forage (sc. 704) in rasht region, an experiment based on randomized complete design with four treatments and three replication was conducted in 2007 growing season, at research farm of faculty of agriculture, university of guilan. experimental treatments consisted of: no-irrigation, 1...

This research involved in and coordinated multidisciplinary and complementary natural resources in the area of sustainable soil and plant nutrient management as well as economic benefits of edible herb production systems. The main concern was selection of the right growing media to achieve optimum yield and growth rate while avoiding application of synthetic fertilizers.Froriepia subpinnata is ...

a greengouse experiment was conducted to evaluation of salinity stress on growth parameters of two olive cultivars during 2013-2014 at agricultural and natural resources research center of tehran. in the experiment, effects of five levels of irrigation water salinity including 0, 4, 8, 12 and 16 ds.m-1 were evaluated on ʻzardʼ and ʻmissionʼ olive cultivars under soilless culture. data showed th...

The effects of varying irrigation intervals (I) and foliar application of salicylic acid (M) on morphological and physiological traits of Catharanthus roseus L. were studied in a factorial experiment based on a randomized complete block design with three replications. The experimental treatments consisted of four irrigation intervals [2 days (I1), 4 days (I2), 6 d...

A field experiment was conducted on the Effect of phosphorus fertilizer and seed rates growth yield common bean (Phaseolus vulgaris L) at Farm agriculture faculty Kunduz University during spring season 2023 to determine optimum for maximum in northeast Afghanistan (Kunduz province). The treatment consists three levels (0kgP2O5ha-1, 40kgP2O5ha-1 80kgP2O5ha-1) four combined (125 kgha-1, 150 175 k...

This experiment was conducted to study the effect of cocopeat: perlite medium with three ratios (v/v) (1:1, 3:1 and 1:3) on some vegetative, flowering and biochemical parameters of two gladiolus cultivars (Strong and White) under soilless conditions in 2016. Data indicated that most vegetative parameters expressed as plant height, leaf number and leaf area, flowering parameter such as spike eme...

Leaf nitrogen (N) and phosphorus (P) have been used widely in the ecological stoichiometry to understand nutrient limitation in plant. However,few studies have focused on the relationship between root nutrients and environmental factors. The main objective of this study was to clarify the pattern of root and leaf N and P concentrations and the relationships between plant nitrogen (N) and phosph...
